+++ This bug was initially created as a clone of Bug #1221100 +++

Description of problem:
======================
Directory has become stale while renaming files in it. Created 2000 files and
renamed 1000 of it. Only 164 has succeeded while the remaining failed.
Accessing the directory gives input/output error. This is on fuse mount while
the same directory can be accessed from NFS mount.

[root at rhs-client29 fuse]# ls -ltrh
ls: cannot access renames: Input/output error
total 128K
